In the bustling streets of Baghdad, where the skyline is rapidly changing, the impacts of urban expansion are becoming increasingly evident, particularly for the agricultural sector. A recent study led by Yusra K. H. Moussa from the Department of Remote Sensing & GIS at the University of Baghdad has shed light on how this urban sprawl is driving temperature increases and altering the climate landscape of the city.
Over the last four decades, the transformation of agricultural land into concrete jungles has not just reshaped the city’s topography but has also contributed to the formation of urban heat islands. This phenomenon, where urban areas become significantly warmer than their rural surroundings, poses serious challenges for local agriculture. As temperatures rise, the delicate balance that crops rely on can be thrown into disarray, potentially leading to lower yields and affecting food security.
Moussa’s study, published in the Iraqi Journal of Physics, utilized ArcMap GIS technology to analyze changes in land use and temperature rates from 1981 to 2021 across three municipalities: Al-Kadhimiya, Al-Shaala, and New Baghdad. The findings were striking. “We observed a clear, direct relationship between urban expansion rates and rising temperatures,” Moussa stated. “This is crucial for understanding how urban planning can impact agricultural viability in the region.”
The data revealed that New Baghdad experienced the highest temperature increase, coinciding with an expansion rate of 92.1. In contrast, Al-Kadhimiya, which is situated along the Tigris River, showed the lowest temperature increase despite its own significant urban growth. This spatial variability highlights the need for tailored approaches in urban planning, especially in areas where agriculture remains a vital part of the economy.
For farmers and agribusinesses, this research opens up a dialogue about adaptation strategies. As urban areas encroach on farmland, understanding these climatic changes becomes essential for developing resilient agricultural practices. Farmers may need to consider shifts in planting schedules, crop varieties, and irrigation techniques to cope with the changing environment.
The implications of this research extend beyond mere academic interest; they touch on the livelihoods of those in the agricultural sector and the broader food supply chain. With urban heat islands intensifying, the pressure on agricultural productivity may escalate, prompting stakeholders to rethink land use and resource allocation.
As cities like Baghdad continue to grow, the intersection of urban development and agriculture will be a critical area of focus. The insights from Moussa’s study not only highlight the immediate challenges posed by urbanization but also serve as a call to action for policymakers and farmers alike to collaborate on sustainable solutions that safeguard both urban and agricultural futures.
